n to the presence of
twelfth-century remains, the curve of the old encircling apse, and the
position of the first sills, abaci, and string-courses. But it should
be noticed that in the eastern bay of this aisle externally, where on
the south there is a fifteenth-century solid square panel, on the
north there is a small round-headed window. But this little window is
of no earlier date than the walls in which it is set. The second and
third windows from the east buttress of the presbytery aisle are
insertions of fifteenth-century type; but they have been so much
renewed and restored that only in the third one does there appear to
be any portion of the original tracery remaining. On the north side of
the choir and presbytery are four very fine old lead rain-water heads
and square lead pipes.

The east end of the present #Library# has in it five windows. Two
of the upper ones are built up, the central and higher one only being
glazed. In detail they are all of the same date as the walls they are
in. None has any tracery, and by this they show that this piece of
work was done at the same time as the chapel--now a vestry--on the
east side of the south end of the transept. The gable is a low slope
like the present roof, but the slope of the old gable and roof may be
seen upon the east wall of the transept. There is one buttress only on
the east side of the library. The north side is divided into two parts
in its length by a buttress. The parapet has a corbel course similar
to that on the two eastern bays of the presbytery aisle. The two small
pointed windows below it are built up, as now the apartment they once
lighted is a lumber-room, where the remnants of the old reredos are
stored. The larger windows below are of the same date, nearly, as
those two fifteenth-century ones in the north wall of the presbytery
aisle. The east one has three and the west four lights, with cusped
tracery in the heads.

The east wall of the north arm of the #Transept# has a buttress, as
is the case with the south arm. But early thirteenth-century pointed
windows take the place of the round-headed ones. There are, however,
three string-courses on this wall of the north arm which do not appear
on the south. One is the old twelfth-century string which evidently
once ran along above the old round-headed windows. The next is a
continuation of the abaci of the capitals. The other passes under the
sills of the windows. A comparison of this wall with th
